摘　　要：对面向工业现场监测的无线传感器网络进行了分析,根据实际需求,以节约能耗为主要目标分别对网络分簇算法和簇间传输路径进行了优化设计。基于HEED分簇算法进行节点分簇,使得簇首节点较平均地遍布整个网络,并解决了边界区域可能出现的孤立节点问题;基于Dijkstra单源最短路径算法对簇间传输路径进行了优化设计,约束经过每个簇首节点的最大节点数,避免单个节点的过度消耗。经对比分析,文中的设计方案可有效节约节点的能量、均衡网络中各节点的能耗,延长网络的生存时长。The wireless sensor network structure for industrial field monitoring was analyzed.According to the actual demand,optimization design was carried out on the clustering algorithm and transmission path between cluster with the main objective of save energy consumption.Clustering nodes were based on the HEED clustering algorithm,making the cluster head nodes throughout the entire network evenly and solving the isolated nodes problem that may arise in the border region.The transmission path between cluster was designed based on the Dijkstra＇s algorithm,constraining the maximum number of connected nodes for each cluster head to avoid excessive consumption of single node.By comparative analysis,this design scheme can effectively save the energy of nodes,balance the network energy consumption and extend the survival duration of the network.
